Overview
Shanghai PUSHEN GJ-2 (1.0-1) grinding Glass bead is a colorless, transparent, smooth and round sphere without obvious bubbles or impurities. It is made of borosilicate Glass, which has the characteristics of good toughness, wear resistance, good chemical Stability, etc. The pH value is 7.2. This product is suitable for grinding medium and low viscosity materials, and can also be used as shot peening beads.
Features
1. Smooth surface, uniform size, high Hardness, wear resistance and stability.
2. High rounding rate, rounding rate ≥ 80%.
3. The density is moderate, 2.4-2 g/cm ³.
4. High refractive index, Nd ≥ 1.50.
5. High compressire strength, > 1200N.
6. Mohs Hardness is high, 6-7.
7. Good Chemical Stability, pH value = 7.2.
8. Good toughness and wear resistance.
Principle
Grinding Glass beads as a grinding medium, in the dispersion equipment (such as sand mill), through high-speed movement and material collision, shear and friction, so that the particles in the material are refined and dispersed evenly, to achieve the purpose of grinding and dispersion.
Applications
Dyestuffs, paints, inks, chemicals
